The performances from Kris Medlen and Paulo Orlando defined the final win in the Royals’ three-game sweep over the Chicago — a sweep that pushed Kansas City to 66-44 and to a season-high 11 1/2-game lead in the American League Central. The 5-4 victory also offered a window into the possible value of Medlen, who worked a season-high 3 2/3 innings after debuting with the Royals on July 20.
